Cargo Transport Trailers

  • DOT MC331, 338, 406, 407,412 
    LPG, Anhydrous Ammonia, Carbon Dioxide and Chlorine transport trailers: semi & bobtail; cryogenic transports; complete design and stress analysis. Analyzed / verified design load cases for cargo trailers per DOT 406, 407 and 412 specs. Optimized tandem axle and kingpin location to maximize shipping volume to comply with inter-state bridge weight rules.

Intermodal Shipping Containers

Dry Cargo Container design and analysis; Tank Container design and stress analysis - minimum weight design and testing. ISO Tank containers (DOT Spec 51, IM01, IM02 and IM05) for liquified gases, industrial chemicals and food products. Also designed / drafted ISO refrigerated and non-refrigerated freight containers to DOD standards.

Verified compliance with international shipping codes (IMDG, RID, ADR, etc). Performed liaison work with certification agencies (American Bureau of Shipping, Lloyd's of London and Bureau Veritas). Managed physical testing of above containers to ISO standards. Engaged by international trade organization: IICL to determine the effects of damage on ISO shipping containers; combined finite element analysis and test laboratory analysis effort, assisting in implementation of finite element computer generated data to establish damage criteria.

 

  • CONTAINERS:  Designed, analyzed and tested ISO Tank Containers and Dry Cargo Containers, 20 and 40 foot. 
     
  • CHASSIS:  Designed truck trailer chassis for containers: 20, 40 and 45 foot.  
     
  • CHLORINE TON CONTAINERS:  Designed / drafted chlorine ton containers per DOT 106A and 110A specs. Also designed stacking frame for shipping / storage.
